Send WhatsApp medication reminders and caregiver alerts with WATI and Google Sheets

💊 WhatsApp Medication Adherence & Caregiver Alert Automation

Ensure health and safety with a fully automated medication adherence system. This workflow manages the entire patient care cycle—from scheduled dosage reminders to interactive logging and automated caregiver escalations—all through WhatsApp using WATI and Google Sheets.

🎯 What This Workflow Does

Turns WhatsApp into a proactive health assistant and caregiver's dashboard:

📝 Timed Dosage Reminders
A scheduled trigger fires 3x daily (Morning, Afternoon, Night) to identify which medications are due and send personalized WhatsApp alerts.

🚦 Smart Patient Routing
A Switch node detects patient replies to manage their health data in real-time: taken: Logs the dose as complete and updates the patient's "Streak". skip: Records the skipped dose and empathetic feedback while checking for consecutive skips. snooze: Schedules a 30-minute follow-up reminder. mystats: Generates a 7-day adherence report with visual progress bars. mymeds: Provides the full daily medication schedule and instructions.

👁️ Automated Caregiver Alerts
An hourly check detects "Pending" reminders. If a patient hasn't responded within 2 hours, the bot automatically alerts the designated caregiver via WhatsApp.

📊 Comprehensive Analytics
Caregivers can request a full patient report (e.g., report <phone>) to view a categorized summary of taken vs. missed doses.
